Turkish Physics Olympic Questions (The original question 13) I am waiting solutions since 2 months but they didnt publish. I can't sleep nights because I didnt solve problem 13

Lets suppose the elevator moves with constant velocity downward and a man press the button to stop elevator then elevator makes slowing down motion downward with a=6m/s2 and angle and height for the object changes with the time.
solution how to? g'=16m/s2 is correct
N-mg=ma+(m/r)Vfinal^2
Energy equation? m(g+a)Integral(rdr)? Because The height is changeabele for every second This is Turkish Physics Olympiad Question. I couldn't solve
Or (1/2)mV^2 +m(g+a)Integral(rdr)= (1/2)mVfinal^2
An elevator slows down with a 6 m/s2 acceleration and an object m=3 kg is freely released as shown in figure There is no friction between object an semispherical shape.
The object reaches L point what is the force which the object exerts L point?
A)120 N
B)240 N
C)360 N
D)480 N
E)600 N...
